JOHN STEPHEN SEWELL, OF THE. UNITED STATES ARMY.

WIND-STRIP.

of the United States, residing at Washing-- ton, District of Columbia, have invented certain new and fusefulImprovements in Windin such walls.

Strips, of which the fol tion. I

The invention relates to door and W'IIlClOW frames when combined with masonry walls, for the purpose of preventing the leakage of wind, cold air, light or dust between such wall and frame.

Theterm masonry is used to include stone, brick, concrete or equivalent material, and it is to be understood that the invention is applicable to exterior or interior walls, wherever an objectionable space is liable to be left between thewall and such frame, either from want of close fitting or from the shrinkage of the frame, or from cracking or displacement of the wall.

The invention is useful with wood or metal frames, a leakage space being often formed or left around the latter due to indifferent workmanship or to the bending or warping of the metal.

It is well known that, especially in cold and windy weather, a great deal of. cold air enters into buildings, not only between the doors and windows and their frames, but also between the frames themselves and the Wallsf In such instances dust is almost always carowing is a specificaried inward by the wind and evidences the leakage, by soiled streaks on the walls extending from the inner edges of the architrave or trim, and from the lower edges of the aprdns under the sills. Efficient forms of weather strips have been devised to prevent leakage between the doors and the window sashes and the frames thereof, but a great source of cold, annoyance and want of economy remains at the present day by reason of the entrance of col air, above referred to, between the'masonry walls and the frames that are supposed to be fitted in an air tight manner into the door and window openings Such leakage is a source of very great expense, in the heating of buildings, and in many cases great cost has been incurred in the tearing out of plastering around window frames for the purpose of stopping such leakage by fibrous substances or packings.

The present come, at slight initial expense and ina per- Specification of Letters Patent. 4 Application filed May 31, 1907. Serial No. 376,552

manent manner, the difiiculties above referred to, and consists, essentially, in the combination of a thin sheet or strip of metal or other permanent and non-shrinking material, with the mason-ry'wall'and frame in such manner that it can be seated in a recess or joint of the wall and extend past a portion of the frame. The wind strip is independent of the frame but engages the same so asto form an airtight joint therewith, and is embedded in the mortar ofv the masonry joint, thus making a wind tight connection with the wall also.

The invention more particularly consists in the parts and combinations thereof herein; after set forth and claimed.

' In order to make the invention more clearly understood I have shown in the accompanying drawings means for carrying the same into practical effect, without limiting my improvements, in their useful applications, to the particular constructions which are hereinafter illustrated and described by way of example.

In said drawings-Figure 1 is a front elevation of a window frame, partly broken away, having attached thereto a wind strip,

showing the same ready for insertion intothe window opening of a wall according to my invention. Figs. 2 and 8 are cross sectional views on lines II and III of Fig. 1,

showing also a portion of the wall. Fig. 4 is an end view of one form of the strip, similar to that'shown in Fig. 9, on a larger scale, in'

applying the strip. Figs. 7 and 8 are hori' zontal sectional views o a door frame showing two ways of applylngl the strip. Fig. 9 is t a similar view showing e frame and strip as ap lied to a concrete wall.

masonry wall, having joints therein indicated at' 2.

3 is the opening in the wall, which is 'here. .shown as a window, opening, but which is-to be understood as typical'of a door or other opening.

eferring to the drawings, 1 indicates the Y 4 is a frame, which may be of wood, metal I or other material, of any suitable shape and construction, fitted in the opening 3.

. 5 indicates a recess in the wall at or: around the opening 3, and which is preferably situthe wall.

'past a portion of the frame.

ated where a joint occurs in the masonry of In the case of a concrete Wall such a recess may be left in the construction of the -wall, or provided, but ordinarily the concrete wall will be filled in around the frame and strip.

6 is a recess in the frame 4, which may be formed in a portion of theframe or which may be provided where'a' joint occurs between two members of the frame.

7 is the wind strip, preferably of metal,

such as zinc or galvanized'iron, which is inthough for certain purposes it is preferred. to

' case not in line with each other but bend both edges ashereafter described. Or the wind strip may be bent into ,L or other shape as indicated in Figs. a, 5, 6, 7 and 9.

To accommodate a strip having its middle portion bent in this manner the frame may be provided with a space or shallow recess 8 parallel with the face of the opening 3 (Figs. 5, 7 and 9) the recesses 5 and 6 bein in such heing' arranged at the two ends of'the space 8. The inner end or edge of the strip, being the edge which is seated in the frame, is or may be provided with a bent edge or flange 10 extending into the frame in a direction parallel with the face of the opening 3 (Figs. 2, 3 and 8). It will thus be seen that the recess 6 in the frame 4 may extend straight into the frame in a direction at right angles to the side face of the opening 3, or may extend into the frame parallel with the face'of the opening 3,

or may have a right angled form between two parts of such frame (Figs. 3 and 8).

11 indicates nails, which are the preferred means for securing the strip to the frame for greater convenience. But it will be understood that the improvement includes such a stripwhen fitted to the wall and frame as described with or without securing means. For more secure and close interlocking with the wall 1 the strip 7 is or maybe rovided with a hook-like edge flange 12; fter the strip has been applied to the frame I prefer to white-lead the recess 6 of the frame at one or both sides of the strip to insure an airti ht joint. Whenthe stripis combinedwith a ollow or other casing having joints through which air might ass, the strip is applied at the outer or win Ward side of such joints, as shownin Figs. 2 and 6.

'The" material used for the strip is or may stone wal the ordinary procedure is to take.

the frame, having the strlp 7 applied and attached thereto around all four sides of the frame, and set it on the wall where the opening 3 is to be made,the strip at the bottom of the frame being caused to enter a joint of the completed wall. bent, if necessary, to cause its outer edge to be in the same vertical plane as suchjoint.

Similarly the side and top strips will be bent, if necessary, to cause them to conform to the planes where the masonry joints at the sides and top of the frame will occur, according to the proposed construction. of the wall. The wall may then be completed around the frame in the usual manner.

The mortar of the masonry joint I into which the strip 7 is inserted performs the two functions of connecting the parts of the ma- This bottom strip will be sonry and of forming an air tight filling around the edge of the strip.

What I claim is 1.- A door or window frame, having a wind strip comprising a flange embedded in the frame, a part which is parallel with a portion of the frame and an outstanding flange or extension, the wind strip being ermanently secured to the frame, in com ination with a wall having an opening for the said frame and a recess in the boundary surface of the opening into which recess the said flange or extension projects and closely fits, substan tially as set forth.

2. The combination of a door or window frame, a masonry wall having an opening for the said frame, and the wind strip extending across the joint between the frame and the wall and tightly fitting into the frame and embedded in the wall, substantially as set forth. j

3. The combination of a door or window frame, a masonry wall having an opening for the said frame, and thewind strip extending across the joint between the frame and the wall and tightly fitting into the frame and embedded in the plastic material of the Wall, substantially as setforth.

In testimony whereof I aflix my in presence of two witnesses.
